复习动词不定式不定式由“t+动词原形”构成,其否定形式是“nt t+动词原形”。不定式可以加宾语或状语构成不定式短语,它没有人称和数的变化,但有时态和语态的变化。动词不定式的用法如下:1.作主语(1)动词不定式作主语时,一般表示具体某一次的动作。若不定式太长,常用it作形式主语而将不定式后置。T see is t believe.眼见为实。It is generally cnsidered unwise t give a child whatever he r she wants.孩子要什么就给什么,被普遍认为是不明智的。
(2)在“It is/was+adj.+fr/f sb t d sth”结构中,若形容词侧重于评价人物的特性、特征,则构成不定式复合结构的介词应用f,此时形容词常为kind、nice、flish等词,且sb与形容词之间可构成逻辑上的系表关系;若形容词侧重于描写不定式动作的特征、特点,则构成不定式复合结构的介词应用fr。It is generus f him t cntribute s much.他捐献了这么多真是太慷慨了。It was imprtant fr us t live a lw-carbn life.过一种低碳生活对我们来说很重要。
2.作表语(1)表示预定要发生的动作。Our schl sprts meeting is t take place n Friday.我们学校运动会将在周五召开。They are t meet at the entrance t the cinema.他们要在电影院入口处集合。(2)当主语是aim、purpse、idea、plan、wish、decisin、chice等词时,常用不定式作表语。His wish is t be an astrnaut in the future.他的愿望是将来当一名宇航员。Her dream is t becme an English teacher.她的梦想是当一名英语老师。

3.作宾语(1)只接不定式作宾语的动词:agree、intend、plan、demand、prmise、prepare、decide、refuse、chse、wish、hpe、expect、fail (未能)、pretend、manage、determine、beg、arrange、threaten、claim、hesitate、wait、happen (碰巧)等。She seated herself at a small table in the restaurant,waiting t be served.她坐在餐馆里的一张小桌子旁等着被服务。The Brwns decided t g n a hliday this summer.布朗一家人打算今年夏天去度假。

4.作宾语补足语(1)不定式作宾语补足语时,宾语和不定式之间在逻辑上是主谓关系,不定式表示将要发出的主动动作。常接不定式作宾语补足语的动词(短语):advise、allw、ask、beg、cause、encurage、expect、frbid、frce、intend、invite、rder、persuade、prefer、require、remind、tell、want、warn、wish、call n、depend n等。Tell yur child clearly and firmly that yu expect them t d their hmewrk respnsibly.清楚并坚定地告诉你的孩子你希望他们认真做功课。Having finished her prject,Prfessr Smith was invited by the schl t speak t the new students.完成项目之后,史密斯教授被学校邀请去给新生讲话。

5.作定语(1)不定式作定语通常放在所修饰词之后,表示将来的动作。不定式与其所修饰的词之间往往是动宾关系,若该不定式是不及物动词,其后应有必要的介词。Suddenly a gd idea ccurred t her,but she culdn’t find any paper t write n.突然她想到了一个好主意,但是她找不到纸把它写下来。
